echo (strlen(the_title())>50) ? (substr(the_title(), 0, 50) . "...") : the_title());

Answer 2

WordPress has built in function "wp_trim_words()" to trim the sentences based on the number of words you provide, If you want to trim by words then this function may help you.

to trim the title longer than 5 words you can do this

<?php
$title = get_the_title();
$short_title = wp_trim_words( $title, 5, '...' );
echo '<h3>'.$short_title.'</h3>';
?>

Answer 3

use 'strlen'

eg: 

  <?php echo ((strlen(get_the_title())>50) ? (substr(get_the_title(), 0, 50) . "...") : get_the_title())?>
